Kinda of Agnostic but my mindset is even if there is no afterlife there is still your legacy. All the good and crappy things you ever did, how they changed people for the better or worse, etc. That being said, honestly my guess would be in some sense living with your descisions in life, you create your personel hell or heaven through your own actions. Obvisouly no way to verify that but I kinda of live by that mindset for the simple fact that even if there is nothing in the afterlife you can at least feel some sense of peace near the end.
